KDA: A Knowledge-Distilled Attacker for Generating Diverse Prompts to Jailbreak LLMs

Buyun Liang, Kwan Ho Ryan Chan, Darshan Thaker +2

Jailbreak attacks exploit specific prompts to bypass LLM safeguards, causing the LLM to generate harmful, inappropriate, and misaligned content. Current jailbreaking methods rely h…
